Wireless monitoring system consists of three parts:
â— Front-end: The camera, lens, pan/tilt, and decoder are the same as the closed-circuit monitoring system.
â— Terminals: Controllers such as hard disk recorders, monitors, or televisions, and matrixes, are the same as closed-circuit monitoring systems.
â— Transmission channel:
Including two subsystems:
1 microwave image transmission system ------ used to transmit the monitoring point image to the monitoring room.
2 wireless data transmission system ------ used to control the room control commands transmitted to the monitoring point, in order to achieve control points PTZ, lens and other wireless control.
The wireless transmission part is divided into two kinds of transmission forms:
1. The transmission and reception of wireless analog microwave transmission images can only be one to one. There can be one to many instruction devices, only one command transmitter, and multiple command receivers. Analog microwave transmission, no distortion and no delay.
Advantages: Strong anti-interference ability, stable signal, clear image and many channels. General composition: transmitter, receiver, relative feeder, filter amplifier, two antennas.
2. Wireless digital microwave transmission Wireless digital microwave transmission (HS-5828T), also known as wireless digital bridge. Digital microwave transmission systems can be networked and can be one to many. No need to command equipment, can automatically control the PTZ, can be directly connected to the computer, using POE power. Digital microwave equipment is generally divided into two frequencies of 2.4G and 5.8G. Wireless digital microwave transmission equipment can be point-to-point, point-to-multipoint transmission. It is also possible to transmit networks and do network coverage.
3. Nowadays, 3G wireless video transmission devices are becoming more and more widely used.
